ABSTRACT:
The effects of
dietary garlic (Allium sativum)
powder as a feed additive on hematological and biochemical health
characteristics of European Sea bass Dicentrarchus labrax juveniles were
studied. Experimental fish were fed diets supplemented with garlic powder at 0
(control), 2%, 4%, or 6% levels for a period of 60 days. Results showed that
the red blood cell count (RBC), hemoglobin (Hb) concentration, hematocrit (%),
and mean corpuscular Hb in fish fed garlic powder diets at dietary inclusion
levels of 4% and 6%, were significantly lower than the control values. Serum
glucose was significantly lower in Sea bass that were fed garlic powder diets
(4% and 6%) compared to the control group. Serum triglyceride and globulin
levels in fish fed a 4% garlic powder diet were significantly higher than the
control values, whereas these two variables in the 2% and 6% garlic treatments
were similar to the control values. The cholesterol levels in the 2% and 6%
treatment groups were lower than the value recorded for the control group. As a
result, it is suggested that garlic powder supplementation in diets for Sea
bass juveniles should not exceed 2%. The present study is the first attempt to
examine the effects of dietary garlic powder on the hematological and
biochemical status in Sea bass juveniles.
